Sparidae (Porgies)
Etymology: Diplodus: Greek, diploos = twice + Greek, odous = teeth (Ref. 45335).
More on author: Linnaeus.
Taxonomic Remarks
This subspecies is reported to have no genetic difference between the subspecies Diplodus sargus cadenati. See V.S. Domingues et al. 2007. Journal of Experimental Marine Biology and Ecology 346 (2007):102-113 (F. M. Porteiro, pers.comm. 02/08). Presence in Canary Is. to be reviewed since D. bellottii and D. cadenati are recognized as valid species, not any more as subspecies of D. sargus.

Duri punggung (Keseluruhan (total)) : 11 - 12; duri punggung lunak (Keseluruhan (total)) : 12 - 15; Duri dubur: 3; Sirip dubur lunak: 11 - 14. Body with 5 black and 4 grey vertical bands. Snout is longer than the eye diameter (Ref. 35388).
Body shape (shape guide): fusiform / normal.
Inhabits coastal rocky reef areas (Ref. 12460) and Posidonia oceanica beds. Like other sparids, it is very active and frequents the surf zone, primarily at dawn (Ref. 13780). Feeds on shellfish and other benthic invertebrates which it picks from the sediment (Ref. 5377).
Sexes separate or protandrous (Ref. 4781). In some areas, this species occurs as a digynic hermaphrodite, that is, males and females developing from intermediate juveniles (Ref. 52202). However, protandry with possible digyny was later confirmed (Ref. 103751). Reaches sexual maturity at 2 years, with an approximate size of 17 cm. Spawning happens from January to March. Egg size 0.8-0.9 mm; larval length at hatching 2.6 mm. Also Ref. 28504.
